bitcoin-qt sucking up all my cpu

[jdough]

hello

i installed bitcoin-qt (0.8.2) for mac osx (mba), and whenever i run it, it takes up all the cpu. is this normal or happening to anyone else? maybe i am missing a setting somewhere?  as a side note, i found a nice free command line tool to throttle processes http://www.willnolan.com/cputhrottle/cputhrottle.html that seems to work well.

cheers.
